Sierra 118-6070 Zinc Trim Tab Anode for Yamaha Outboards

The Sierra 118-6070 is a zinc sacrificial anode designed specifically for Yamaha outboard motors. This trim tab anode mounts to the lower casing drive unit to provide critical corrosion protection for your outboard's metal components in saltwater environments.

Key Features:

• Premium zinc construction for effective galvanic corrosion protection in saltwater
• Direct replacement for Yamaha OEM part numbers 688-45371-02-00 and 67F-45371-00-00
• Installs on the lower unit drive casing of compatible Yamaha outboards
• Meets or exceeds original equipment specifications
• Acts as a sacrificial component to protect engine parts from electrolysis

Sacrificial anodes are essential maintenance components that deteriorate over time to prevent galvanic corrosion damage to more expensive engine parts. This anode is engineered specifically for saltwater use and should be inspected regularly and replaced when 50% degraded to ensure continuous protection of your outboard's critical metal surfaces.
